Virtual Magnetic Imaging Logs: Generation of Synthetic MRI Logs from Conventional Well Logs
Proceedings of SPE Eastern Regional Meeting, 1998Abstract MRI logs are well logs that use nuclear magnetic resonance to accurately measure free fluid, irreducible water (MBVI), and effective porosity (MPHI). Permeability is then calculated using a mathematical function that incorporates these measured properties.

Fourier signature in log-polar images.
2007Inimage-basedrobotnavigation,therobotlocalisesitselfbycompar- ing images taken at its current position with a set of reference images stored in its memory. The problem is then reduced to find a suitable metric to compare im- ages, and then to store and compare efficiently a set of images that grows quickly as the environment widen.

Straight Lines and Circles in the Log-Polar Image
Procedings of the British Machine Vision Conference 2000, 2000Foveal or spatially-variant image representations are important components of active vision systems. Log-polar sampling is a particularly powerful example as a result of the simplicity with which expansion and rotation can be handled. These properties are exploited here for the detection of general straight lines, line segments, and circles through the

Log Analysis of Multilingual Image Searches in Flickr
2009In this paper, we summarize our analysis over the logs of multilingual image searches in Flickr provided to iCLEF 2008 participants. We have studied: a) correlations between the language skills of searchers in the target language and other session parameters, such as success (was the image found?), number of query refinements, etc.; b) usage of ...
